Oct. 20, 2016

Komatsu Ltd. (Head office: Minato-ku Tokyo, President and CEO: Tetsuji Ohashi, hereafter "Komatsu" or "Company") announced in its press release dated July 21, 2016, titled "Komatsu to acquire U.S. mining equipment manufacturer Joy Global" that it will acquire Joy Global Inc. (Head office: Wisconsin, USA, CEO: Edward L. Doheny II, hereafter "Joy Global", NYSE) through Komatsu America Corp. (Head office: Illinois, USA, Chairman and CEO: Rodney Schrader, hereafter "KAC"), a wholly-owned subsidiary of Komatsu in the USA (hereafter "Acquisition"). Komatsu is pleased to announce that the merger agreement for the Acquisition was approved at the extraordinary shareholders meeting of Joy Global which was held on October 19, 2016 (local time). The Acquisition is expected to close, subject to satisfaction of customary closing conditions, including the receipt of necessary regulatory clearances under competition laws in relevant countries. Please see "Future Outlook" below for the expected completion date of the Acquisition.

Future outlook

After the Acquisition is complete, Joy Global will become a consolidated subsidiary of Komatsu. The expected completion date is not yet fixed because it may change depending on the timing of the receipt of necessary regulatory clearances under competition laws in relevant countries. Such regulatory clearances were received in the USA and Canada on October 12, 2016 and October 14, 2016 (local time), respectively. The completion of the Acquisition may occur within Komatsufs fiscal term ending March 2017 depending on the progress of the remaining regulatory clearance procedures. If the Acquisition is complete during Komatsufs fiscal term ending March 2017, there may be an impact on the consolidated results and performance of Komatsu for the fiscal term ending March 2017, but details of any such impact remain unknown at the present. The Company will make a disclosure of the impact of the Acquisition on its consolidated results and performance in a timely fashion as the closing procedure moves forward.
